Please, we need that error message word-for-word. However, it sounds like an issue about heap memory (RAM).
You should ask the author of that game if that issue is known or the availability for a Nokia 309 was a mistake. If you are really curious, did you apply the Nokia Software Recovery Tool already? Then, you know it is not a software/configuration issue on your behalf. Then it is either a hardware issue in your particular device, something is broken – or the author made a mistake.
Availability of the apps will depend on the app developer. Phone capabilities to handle such apps may also vary. You may try checking the store for the alternative apps. Otherwise, reach out to the app developer.
If that and time is correct, which network operator do you use in which country?
Did you consider the Nokia Software Recovery Tool on a Windows computer already?
You applied the tool and you still face that issue? Then, please, remove the SIM and use Wi-Fi to download the latest Nokia Store. Did that work/help?
You could try another SIM.
We have some reports, that some SIMs do block the phone internal certificate-authorities for code-signing. That is a software-bug, not intentional. To rule-out this bug (you might not face this bug), the next step would be ‘without SIM and a Wi-Fi’.
